When add_dquot_ref() fails (usually due to IO error or ENOMEM), we want to disable quotas we are trying to enable. However dquot_disable() call was passed just the flags we are enabling so in case flags == DQUOT_USAGE_ENABLED dquot_disable() call will just fail with EINVAL instead of properly disabling quotas. Fix the problem by always passing DQUOT_LIMITS_ENABLED | DQUOT_USAGE_ENABLED to dquot_disable() in this case.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
